New Delhi, Mar 21: A couple was deboarded from a Delhi-bound Rajdhani train on Saturday after co-passengers observed a home quarantine seal on the husband's hand, the Railways said Saturday.

Officials said the Delhi-based couple boarded the Bangalore City-New Delhi Rajdhani at Secunderabad on Saturday morning.

When the train reached Kazipet in Telangana at 9:45 am, a co-passenger noticed the quarantine mark authorities are putting on suspected coronavirus cases —on the husband's hand when he was washing his hands. Other co-passengers then informed the TTE onboard.

The train was briefly detained and the couple was taken to a hospital. The coach was completely sanitised in Kazipet and was locked, officials said.

The air conditioning was also switched off.

The train left for its destination at 11.30 am.

People fleeing quarantine has been a common problem reported from different parts of the country.

Feb 22: A 20-year-old Chinese woman from Wuhan, the epicentre of the coronavirus outbreak, travelled 400 miles(675 km) north to Anyang where she infected five relatives, without ever showing signs of infection, Chinese scientists reported on Friday, offering new evidence that the virus can be spread asymptomatically.

The case study, published in the Journal of the American Medical Association, offered clues about how the coronavirus is spreading, and suggested why it may be difficult to stop.

"Scientists have been asking if you can have this infection and not be ill? The answer is apparently, yes," said Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, who was not involved in the study.

China has reported a total of 75,567 cases of the virus known as COVID-19 to the World Health Organization (WHO) including 2,239 deaths, and the virus has already spread to 26 countries and territories outside of mainland China.

Researchers have reported sporadic accounts of individuals without any symptoms spreading the virus. What's different in this study is that it offers a natural lab experiment of sorts, Schaffner said.

"You had this patient from Wuhan where the virus is, travelling to where the virus wasn't. She remained asymptomatic and infected a bunch of family members and you had a group of physicians who immediately seized on the moment and tested everyone."

According to the report by Dr Meiyun Wang of the People's Hospital of Zhengzhou University and colleagues, the woman travelled from Wuhan to Anyang on Jan. 10 and visited several relatives. When they started getting sick, doctors isolated the woman and tested her for coronavirus. Initially, the young woman tested negative for the virus, but a follow-up test was positive.

All five of her relatives developed COVID-19 pneumonia, but as of Feb. 11, the young woman still had not developed any symptoms, her chest CT remained normal and she had no fever, stomach or respiratory symptoms, such as cough or sore throat.

Scientists in the study said if the findings are replicated, "the prevention of COVID-19 infection could prove challenging."

Key questions now, Schaffner said, are how often does this kind of transmission occur and when during the asymptomatic period does a person test positive for the virus.

Microsoft's Indian-origin CEO Satya Nadella on Monday voiced concern over the contentious Citizenship Amendment Act (CAA), saying what is happening is "sad" and he would love to see a Bangladeshi immigrant create the next unicorn in India.

His comments came while speaking to editors at a Microsoft event in Manhattan where he was asked about the contentious issue of CAA which grants citizenship to persecuted non-Muslim minorities from Pakistan, Bangladesh and Afghanistan.

"I think what is happening is sad... It's just bad.... I would love to see a Bangladeshi immigrant who comes to India and creates the next unicorn in India or becomes the next CEO of Infosys," Nadella was quoted as saying by Ben Smith, the Editor-in-Chief of New York-based BuzzFeed News.

In a statement issued by Microsoft India, Nadella said: "Every country will and should define its borders, protect national security and set immigration policy accordingly. And in democracies, that is something that the people and their governments will debate and define within those bounds.

"I’m shaped by my Indian heritage, growing up in a multicultural India and my immigrant experience in the United States. My hope is for an India where an immigrant can aspire to found a prosperous start-up or lead a multinational corporation benefitting Indian society and the economy at large".

The Centre last week issued a gazette notification announcing that the CAA has come into effect from January 10, 2020.

The CAA was passed by Parliament on December 11.

According to the legislation, members of Hindu, Sikh, Buddhist, Jain, Parsi and Christian communities who have come from Pakistan, Bangladesh and Afghanistan till December 31, 2014, due to religious persecution will not be treated as illegal immigrants but given Indian citizenship.

There have been widespread protests against the Act in different parts of the country.

In Uttar Pradesh, at least 19 persons were killed in anti-CAA protests.
